arrow-keys

问题 I have built an Android app which loads a html page in WebView, and it is working ok, except the fact that actions should happen on D-pad arrow keys won't work. If I change action for arrows with other keys, it works. Loading the html page in web browser works fine, PC keyboard arrow keys return correct actions, but in Android WebView, D-pad arrow keys aren't working. This is how I tiger key pressed in js: window.addEventListener('keydown', keyDownHandler, true); function keyDownHandler(evt){

问题 I'm using python 2.7 and code ssh client with paramiko library, I use myhost.channel.send(chr(keycode)) to send every keycode to server. But It only works with 1 byte keycodes. I want to send other multi-byte keycodes like arrow keys. How can I achieve this? Please help me. 回答1: A GUI like Windows or MacOS identifies keys with 'keycodes', but an SSH pipe just transfers bytes, not keycodes. Assuming the program running inside ssh on your server is interactive (that is, it's expecting a human

问题 I am making a game in C, and when the user input the Konami code (cheat code), the program should print out the correct answer. (edit #3) found out that my program does not "read" the arrow keys whenever I input it, how do I make it so? pls. see my comment below Here is my updated code (edit #2): //try konami #include<stdio.h> #include<string.h> main() { int c; char cheat[] = {24,24,25,25,27,26,27,26,98,97}; //thanks to Vicky for clarifying this char guess[100]; printf("Enter guess: "); scanf

问题 I want to implement the command line features like in a linux terminal. I saw this in ftp command also. If I press tab I need to list the commands. If I press control characters I need to get that characters based on that I will do some action. And if I give any commands it should execute. For this I tried with Term::ReadKey that is in non-canonical mode. But here I am facing more problems like if I press any control character or arrow I got three characters. For the up arrow I got ASCII 27

问题 I'm building a menu with topics and items. Each topic can be expanded and collapsed by clicking on it. My task is to make it possible to move through menu topics and items with the up and down arrow keys. I've done this already, but the problem is that when the page is bigger than the window, the page is scrolling when pressing the arrow keys. I've tried using: document.body.style.overflow = "hidden"; to stop the page from scrolling. Thus when I click on 'Topic2' for example I can continue

问题 Everytime I use these keys in the interpreter I keep getting symbols like this appearing: [[D^[[C I'm using Linux Mint 12 in ZSH, however I'm getting the same result in Ubuntu with bash. Also, same thing in ssh. 回答1: The stock OCaml toplevel doesn't have line editing built in. I use rlwrap : $ cat bin/ocaml #!/bin/sh exec rlwrap /usr/local/bin/ocaml "$@" Using the toplevel without something like this is quite painful, in my opinion! Other possibilities are to run the toplevel under emacs (a

问题 Is there any way to catch the Up/Down arrow keys in a WPF TextBox ( System.Windows.Controls.Textbox ) and allow them to alter the text? I've read about overiding the ProcessCmdKey method for a Windows Forms TextBox ( System.Windows.Forms.TextBox ), and it worked fine, but that TextBox is not nearly as flexible as the WPF one. Is there a similar method to accomplish this without having to use the old Windows Forms TextBox? For my example, I have a TextBox that has a numeric text-mask. I want
